MISSING function

["Yogesh K. Tiwari" <ktiwari@xxxxxxxxxxxxxxx>]

Hello Ferret Users,

I have netcdf file and after doing ncdump of a 
variable co2, some of the values are -9999.

I want to treat this value as missing value.

I tried to teach ferret this missing value by 
using the MISSING function like :-

let a = -9999
      let missing_default = `a, RETURN=bad`

let co2_default =  MISSING(co2, missing_default)


But the result still includs the missing value 
-9999 in the shade plot and the CO2 values are 
-200,-300 like that whereas my data is ok and have 
no negative co2 value.

Whether I did correctly ?? then why result dosen't 
chang with or without missing function.

Whether ferret like -9999 as missing value ?

Many thanks in advance for your help.

Regards,
Yogesh
